How to Deal with CrystalDiskInfo Shows Caution? Here’s Guide

CrystalDiskInfo is a hard drive health status checker. Many people use CrystalDiskInfo to monitor and display various parameters of their hard drives. However, some people report that their CrystalDiskInfo shows hard drive as yellow caution status. What does this mean? Please keep reading.

CrystalDiskInfo Shows Caution

When CrystalDiskInfo shows Caution, it means that the hard drive performance is degrading and the hard drive is unhealthy. This yellow warning status can be caused by one of these three common errors.

• C5 – Current Pending Sectors: A number greater than 0 in the C5 – Current Pending Sectors column will cause CrystalDiskInfo to issue a warning.
• 05 – Reallocated Sectors: A number greater than 0 in the 05 – Reallocated Sectors row will trigger CrystalDiskInfo’s warning system and issue a warning.
• C6 – Uncorrectable Sectors: A number greater than 0 in the C6 – Uncorrectable Sectors row will trigger CrystalDiskInfo shows Caution.

After encountering this warning, it is best to back up any important data immediately. This will minimize the risk of data loss if the drive fails while in use.

If you want to continue using the drive with these errors, you will need to closely monitor the drive’s health daily and make sure the count in the “Raw Values” column has not increased dramatically. This does not guarantee data safety, however.
